Why ice related services are required?
The Baltic Sea:Heavy marine traffic (largest of ice covered seas in Word)
• Annual 600-700 million tons (of which 40% during winter months)
• Any time 2000 larger vessels are sailing in Baltic Sea
• >90% of ships with timetablesIce navigation obligatoryIce plays a role up to 6 monthsmarine transportation growing 2-5% a year => 30-40% in 10 yearsFinland:
• Annual marine transport 95 million tons of goods (2004), of which
• ~40 mil. tons in winter months with >25 000 port calls
• 8 icebreakers

• 1975 31 mil.tons => 2004 95 mil.tons• Average growth 3-4%/year • 1995-2004 growth 34%• By 2015 133-148 mil. tons/year

Growth scenarios: Marine transportation growth- Finland
•2015 => 800-1000 mil. tons
•Oil transportation from Russia:
•>100 mil. tons in 2005
•>200 mil. tons in 2010
•>400 mil. tons in 2015
Marine transportation growth- Baltic Sea
Latest forecast: by 2015 about 1 B tons!

High-Resolution Ice Thickness Charts over the Baltic Sea
• Ice thickness chart is based on SAR and ground truth.
• Spatial resolution 500 by 500m= product for ships and in ships’ scale.
• End users: shipping
• Motivation easy to use: Growth of marine transportation =>Risk of hazards is growing. Unexperienced crew. Time-lines of ships
• Published when SAR data available (about 250 charts in ice season 2005-06, 200 in 2006-07). In 30 min after SAR data is downloaded
• Future: should be aware of availability and in use of all shipping in the Baltic Sea© Finnish Institute of Marine Research, 2006

Ice forecasts over the Baltic Sea• Covering the Baltic Sea
• End users: shipping
• +45 h in 3 h steps
• resolution 1 nautical mile
• 6 parametres:
– ice concentration and drift
– ice ridge thickness
– ice ridge concentration
– compress region
– deformed ice fraction
– mean ice thickness
• published once a day
• Future: expand of forecast up to 10 days. Should be aware of availability and in use of all shipping in the Baltic Sea

Finnish Meteorological Institute Arctic activities relevant for
EuroGOOS Arctic Task TeamTimo Vihma
1. Research activities in DAMOCLES (Developing Arctic Modelling and Observing Capabilities for Long-term Environmental
Studies)FMI is leading DAMOCLES WP2: Atmosphere, which has the following tasks:Arctic cyclonesOperationally important aspects: Detection of mesoscale cyclones:
- high-resolution buoy network (to be deployed by the University of Hamburg)- utilization of AMSU-B data on total water vapour and cloud water content to help detecting Polar lows
Impact of cyclones on sea ice driftb) Boundary layer turbulence Stably-stratified ABL over sea ice; wind forcing on sea ice drift Localized convection over leadsc) Clouds, adiative fluxes and surface albedo
2. Numerical Weather Prediction including Arctic and sub-Arctic regionsFMI is running the reference version and a meso-β version of HIRLAM:
Plans for joint Nordic production of numerical weather prediction
